It is revealed that Mikado created the Dollars in hopes to create a rumor which would spread, however his plans were brought down when people calling himself Dollars were doing evil. In desperation Mikado left messages about Dollars being a group to do good, which in fact worked. Just as Namie and her followers are desperate, Celty with a high resolution over her existance caring little if she is seen as a monster, decides to attack the Yagiri workers defeating them, although revealing herself as "headless" causing panic among the people.

Six months had passed since the Dollars meeting at Ikebukuro. Since then, the police starts chasing Celty tirelessly through the city, leaded by Kinnosuke Kuzuhara, a reckless police biker specially assigned to aprehend her. After losing their tail, Celty is asked by Shinra to pick his father Shingen who just arrived at Japan. Meanwhile, another urban legend, the mysterious assailant known as "The Slasher" is attracting the media's attention as his/her identity is a mystery, and just when Anri was being bullied by the same girls who harassed her before, The Slasher appears and cuts them down before her.

Anri and several others are attacked by the slasher. Each night someone is attacked, someone called Sinsong appears on the web, writing mysterious messages. "Today. Cut. Did Cut. More. Stronger. Love. Wish. Wish. Is. Want." Mikado is bothered by the rumors that the Slasher attacks are being perpetrated by the Dollars, and asks Celty for help. Celty eventually learns from Shinra that his father Shingen previously acquired a sword called Saika to separate the link between Celty's head from her body, and later had the weapon sold to a second-hand antique dealer. Shizuo offers to help Celty take care of the slasher when she goes out to search for the culprit. As Anri goes back home after parting ways with Mikado and Kida, she ends up at the place where she was spared by the slasher days ago. The slasher comes up behind her and prepares to strike.

A journalist named Shuji Niekawa is beaten up by Shizuo six months ago while trying to research who is the strongest person in Ikebukuro. As he goes around interviewing Simon, Izaya and Celty, Niekawa narrates his feelings on his latest work and the regret of not able to bond with his distant daughter, Haruna. After heading back home from a long day of work, Niekawa is attacked by the slasher who stabs him with a kitchen knife. After he survives the attack with no memory of the incident and awakes in hospital, Niekawa is possessed by the slasher spirit and directed to look for Anri, who was heading back home in episode 14. As he attempts to attack, Kyohei and his gang knock Niekawa down and rescue Anri. However, Niekawa gets back up to attack a second time but is knocked down by Celty on her bike with Shizuo in tow. Upon seeing Shizuo, the demonic spirit in Niekawa professes its love for him. Shizuo is enraged on hearing the slasher's confession and rips out a car door to bludgeon Niekawa.

Just as Shizou defeats Shuji, Celty takes the knife he drops and shows it to Shinra claiming that it could be Saika. Haruna Niekawa the daughter of Shuji comes to visit Anri to discuss about Nasujima, the teacher who harrases Anri. Shinra and Celty discussing about Saika, discover that Saika loves humans so much that it demonstrates her love via actions manipulating her host. They also find out multiple Saikas in the chat room as they find out that Saika slashes humans just as it leaves her "children" to manipulate multiple hosts. Celty decides to go for Shizou who went to fight Izaya who could be a target of Saika, not much later a multitude of hosts get around Shizou claiming they "love" his power. Shizou now liking his own power for the first time decides to fight back. While Nasujima is being chased by a possessed Haruna, Anri is attacked by multiple Saika-hosts. Haruna then is able to corner Nasujima, however Anri asks her to stop slashing people, just as Haruna attacks Anri, she is left unharmed as Anri reveals she is in fact, the wielder of the true Saika.

Sonohara pokes Niekawa with Saika, and shows her a flashback of how she became its wielder. Sonohara's father was an antiquities dealer, and constantly beat up her and her family. Her mother then got possessed by Saika, killed her father, and committed suicide. Sonohara then grabs the cursed blade, and becomes its wielder. Meanwhile, Shizuo beats up Niekawa's "Saika children," flashing back to his past. Sonohara then assimilates Niekawa's Saika, and as a result takes control of all of the Saikas in Ikebukuro. Sonohara apologizes to Celty for attacking her back in Episode 5. Mikado later visits Sonohara at the hospital, and after realizing she has met the "unusual people," warns her to stay away from the non-normal. As a result of Niekawa's assimilation, Sonohara has gained her and all of the Saika's memories; she suspects that Izaya is up to something. Mikado is later shown contacting members of the Dollars, but it is unknown for what reason. The episode concludes, as Izaya's plot deepens further; he is revealed to be behind several events in the slasher arc. He has caused a split of the city's population into different "factions;" Saika/Sonohara's army, the Yellow Scarves, and the Dollars; and knows that they will fight amongst each other. Kida, not knowing Anri Sonohara's true nature, retakes his place as the leader of the Yellow Scarves. He suspects the Dollars to be responsible for Sonohara's injuries, and vows revenge.

While Ryugamine and Kida are walking Sonahara from the hospital after she had recovered, Kida gets a phone call from the Yellow Scarves and he runs off, Ryugamine and Sonahara not knowing anything. Kida, resuming his lead role of the Yellow Scarves, retells his past about him and a girl named Saki who is left in Ikebukoro hospital. While he was in the Yellow Scarves, he met her along with Izaya Orihara who claimed to be her guardian. Whenever Kida was in trouble or needed help with his decisions he always went to Izaya for help but he soon wanted to stay away from he because he thought he was not good. Later on, he begins to date Saki but still wanting her to not hang around Izaya while the Yellow Scarves fight another rival gang, the Blue Squares. Soon later on, the Yellow Scarves start to get beaten up by the Blue Squares, leaving some members injured. When that trouble strikes, he goes to Izaya for help and Izaya trains Kida and the Yellow Scarves and the Yellow Scarves begin to win and Kida becomes more fond of Izaya. One night while Kida was studying, the Blue Squares called his phone saying that they had captured Saki as revenge to the Yellow Scarves since Kida was the leader. They beat up Saki as Kida runs to chase after her. Meanwhile, the Squares tell Kadota about what they have done and ask if he and his gang would join them but he refuses. As Kida runs he stops saying that he couldn't move to save Saki. Walker invades the Blue Squares hideout and he saves Saki and he drives off with Kadota and the rest of the gang. Later on, Saki is put in hospital and Kida tell them that he can't bear to visit Saki because he wants to break up with her. Kida leaves the Yellow Scarves, meets up with Ryugamine and joins Raira academy. Back in the present day, Kida rejoins the Yellow Scarves to take revenge on the Slasher, whom he believes is part of the Dollars, for hurting Sonahara. In the end of the episode, the Yellow Scarves report that they've spotted a girl invading their territory and Kida asks for them to capture her but not hurt her. The girl turns out to be Sonahara who is running away, shocked to believe that Kida is part of the Yellow Scarves.

Anri Sonohara runs away from the Yellow Scarves. She hides in a dark alley and is scared of what will happen if Kida finds out her identity. The scene flashes back to when Anri was fetched out of the hospital by Mikado and Kida. Anri is puzzled over Kida's strange behaviour and worries about causing a gang war over Saika. This prompts her to ask her 'children' in Yellow Scarves who their leader is, not believing it when told it was Kida and decides to investigate. The scene comes back to when Celty sends her a text message and rescues her. As Celty drives away, a Yellow Scarves member throws a metal pipe at Anri, who brings out Saika and slashes it away just in time. Kida comes to the conclusion that Saika is also in Dollars. Meanwhile, Izaya fills Mikado in on the details of the gang war between Yellow Scarves and Blue Square. Kida realizes that he had only fought as the Yellow Scarves's leader for Mikajima Saki, and now his best friend Mikado.

Kida Masaomi looks into matters concerning the leader of the Dollars. He confronts Kyohei Kadota, a former Blue Squares member, about who might know something about this. Walker and Erika are there as well and they lecture Kida about forgetting that the blue squares ever existed since they hurt Saki Mikajima, Kida's former lover. They tell Kida to move on with his life and to forget that incident with Saki ever happened. Kadota gives Kida semi-useful information, but it still isn't enough. Anri becomes uneasy around Kida because she now knows that he is the leader of the yellow scarves. Kida goes to Izaya for advice and there, Izaya reveals to Kida that Mikado is the leader of the Dollars. At the recent meeting for Yellow Scarves, Kida orders everyone not to harm the Dollars yet, since there is not enough information to declare war on Dollars. Meanwhile, a member of Dollars who Mikado and Kida had met before is beaten severely in the streets by several Yellow Scarves members, despite Kida's orders. The next day, Kida tells Mikado and Anri that he will be visiting the hospital to see the injured Dollars member, increasing anxiety on Mikado's part.
